Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.

Update Azure Firewall rules
Why it's wrong here
While Firewall works, NSGs are the granular, VM-level control for this scenario.

Delete the VM's public IP
Why it's wrong here
Deleting the IP is disruptive and unnecessary if a rule can block the destination.
- ✗
Disable the Virtual Network
Why it's wrong here
Disabling the network would take the entire environment offline.

Modify the Network Security Group (NSG) outbound rule
Why this is correct
NSG rules are the direct and standard way to block specific traffic for a VM.
